CG-Ngong : Project Activities
Proposed site for demonstration of wastewater treatment and use of
treated water for crop irrigation.
Problem (09 April): a drain empties sewage
and storm water into a lowland beside CGG-Ngong and created a swamp (Pic 1 on left) of about 400 m2. Overflowing wastewater enters a main
municipal drain further downstream (Pic 2 on right).
A Technical Solution: The problem
could be solved by digging a drain (marked in red)
around the lowland
 to divert
all wastewater directly into the municipal drain. The lowland can
then be used as a constructed wetland to demonstrate treatment of sewage
using plants and
the use of treated water for
irrigation for crops that is grown on its embankments.
